THOMAS G. PARADINE, OF ERIE, PENNSYLVANIA sror-oocx BOX.

Application tiled July 11, 1910; Serial It'd- 5713.

To all whom it may concern."

Be .it known that I, THOMAS G. PARADINE, a citizen of the United States, residing. at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Sto -Cock Boxes; and I do hereby declare the ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it'appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to improvements in metallic casings for stop-cocks which are used to control the flow of water or gas from the main into the service pipes of a building, and which are usually located outside of the building and at varying depths beneath the surface ofthe ground or pavement, rendering it necessary to have some means for permitting ready access to the stopcock or valveto turn the same.

The present invention has for its object to provide a metallic casing in telescoping sections and to provide in the telescope joint between the two sections means whereby the upper section of pipe will be retained in such extended posltion as may be desired without the use of external means for that purpose. These and other features of my invention will appear hereinafter in the specification and claims and are illustrated in the accompanying drawings in which:

Figure 1, is a view in elevation of my improved stop-cock box apart thereof being brokenaway. Fig. 2, is a transverse section of the same on theline wa: in Fig.1, looking downward. Fig. 3, is a like view on the line yy, looking downward.

In these drawings, A,'indicates the lower section of my improved stop-cock box, and B, indicates the upper tubular section of the same which is adapted to telescope into the lower section A, as shown in Fig. 1. C, indicates the valve-stem which is adapted to engage a valve in a service pipe, (not shown) in the usual manner. The upper end of the pipe, B, is closed with a closure plate, 1), all of which parts are of usual and ordlnary construction, except as hereinafter noted and explained.

In setting stop-cock boxes, as usually constructed, the uppersection, B, thereof Wlll not stay in an extended position so that the formed of brass, but

proper placed earth may be filled in around it to the level, un 'ess a prop of some kind is between the bottom of the trench and the cap D and when such a prop is used it-is very dlfiicult if not impossible to remove it after the trench is filled up. For the purpose of causlng the upper section of the stop-cock box to remain in an extended position I make an annular groove, a, in the upper'end of the lower section, A, in which groove I place a spring ring, E, which is adapted to grip the upper section or pipe, B, with sufiicient force to sustain the weight thereof, and thereby prevent the same from sliding downward in the lower section, A, of the stopcock box. Thisspring ring, E, is preferably any metal which will not be destroyed by rust or corrosion may be employed.

To prevent the upper section, B, from turning in the lower section, A, when it is desired to remove or replace the cap, D, thereon, I provide within the'lower section, A, splines or ribs, 0,, and the lower end of the tube, B, is split and flattened sufiiciently to form projecting lips, I), which engage the sides of saidsplines, a and prevent the tube, B, from turning in the lower section, A, of the stop-cock box.

en my improved stop-cock box is being plziced in position for use, the workman has on y stop-cock, connect the stem, C, to the valve then raise the tube, B, up far enough so that the cap, D, will be at the level of the ground or pavement, at which elevation the spring ring, E, will retain it while the workmen are filling in the trench.

Having thus described and illustrated .my invention so as to enable others to construct and use the same, what I desire to secure by Letters Patent is:

1. The combination in a stop-cock box of lower and upper telescopic sections of tub- .mg, a friction ring embracing and automatically clamping the upper section, and means to prevent said ring from moving downward below the'upper end of the lower section, substantially as set forth.

2. The combination in a stop-cock box of a lower tubular section, having an annular groove'around the upper end of the tubular cavity in said lower section, a metallic spring ring in said annular groove, and an upper section of tubing inserted telescoplcally within said lower section so that the same will,

thiough be embraced and automatically clamped by the spring ring in said annular groove, substantially as and for the purpose set forth.

3. The combination in a stop-cock box, of a lower tubular casing having an annular groove around the upper end of the tubular cavity therein, longitudinal splines within said cavity, an upper tubular section having its lower end split and flattened so as to engage the sides of said splines extending said lower tubular section, a closure cap r1n on the upper end thereof, and a spring within said annular groove embracing THOMAS Gr. PARADINE.
